I think it would be interesting to add the redeploy feature in the plugin. I'm new in it, so I'm afraid I cannot develope it by now, but I'm missing this feature in the work I am on charge of.
By console in my local machine I can do that with de command
java -cp C:\Oracle\Middleware\wlserver_10.3\server\lib\weblogic.jar weblogic.Deployer -adminurl t3://192.168.100.221:7001 -user weblogic -password weblogic -redeploy -name UniVicWorkspace -source "C:\Users\516230\.jenkins\jobs\PGU PRODUCTIU\workspace\UniVic.ear" -targets AdminServer -upload
by no way to do the same with the plugin. I'm affraid i will need to create an script to do the task by now.
My ant build file creates me and ear file with the version able to being redeployed without stopping service to clients.
